Build a Loudspeaker Impedance Test Circuit Using a Digital Multimeter & SGenerator

Описание к видео Build a Loudspeaker Impedance Test Circuit Using a Digital Multimeter & SGenerator

A simple circuit to measure loudspeaker impedance using an audio signal generator and a high impedance digital multimeter that reads AC voltage in mV.

If you elect to use a smartphone as a signal generator, you are doing so at your own risk.

Thanks for watching and subscribing to my channel on vintage radio repair.
